If your cat has tummy issues after eating certain foods, they may have a sensitive stomach. This can be caused by food allergies, intolerances, sensitivities to certain ingredients, eating foods that are hard to digest, or by eating low-quality food.
The good news is that there are commercial cat foods available for cats with sensitive stomachs or other gastrointestinal issues, but we recommend talking to your vet if your cat has been showing signs of these conditions. Your vet can advise whether a treatment plan is necessary and can recommend you suitable foods for your cat’s specific condition. In some cases, certain foods can only be purchased with vet approval.
In the meantime, here are our reviews of some of the best cat foods for diarrhea in Canada to give you an idea of what might help with your cat’s tummy troubles.

Buyer’s Guide: Choosing the Best Cat Foods for Diarrhea in Canada
Buyer’s Guide: Choosing the Best Cat Foods for Diarrhea in CanadaWith so many cat food options on the market, knowing where to start can be a challenge. There are a few factors you can consider to narrow down your choices, though. Most importantly, you’ll need to ascertain whether your cat is just a tad sensitive or if they have an underlying health issue that needs addressing.
It’s always best to talk to your vet about digestive issues to make sure your kitty isn’t missing out on important treatment. It’s also the best way to find out which food to get them, as your vet can recommend a suitable formula.
Some vendors require veterinary approval before they will sell you a certain cat food—like a prescription diet—so if you’re purchasing one of these, make sure you have a signed approval or prescription from your vet to show.
You’ll also want to factor in how much you’re willing to spend. As we’ve seen, some brands are a bit less easy on the wallet, so setting a budget can help you narrow down products within a certain range. Your cat’s preferences are also a big factor—some cats are finicky and will only eat certain proteins or brands.
The best way to get an idea of whether a product would be suitable is to check user reviews across a variety of sites. You’re likely to read reviews from people in a similar situation, which is invaluable when you have no idea what brand to go for.
In Conclusion
Time to rewind a bit. Our best overall pick is the highly-reviewed Purina One Sensitive Skin & Stomach Formula. Our best value choice is Blue Buffalo’s Sensitive Stomach with LifeSource Bits formula, and our premium choice is Hill’s Science Diet’s Sensitive Stomach and Skin Formula.
For kittens, we recommend the Hill’s Science Diet dry kitten food which can be paired with Hill’s Science wet food, and our top 5 is Hill’s Science Diet’s Perfect Digestion Formula. We hope you’ve found these reviews helpful in your search for the best cat food for diarrhea in Canada. Good luck!
